CHARLES F. HINTZE, OF ST. LOUIS, MISSOURI.

FOLDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 410,098, dated August 27, 1889.

Application filed November 10, 1888; Serial No. 290,434. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES F. HINTZE, of the city of St. Louis, in the State of Missouri,

have invented a certain new and useful Im-.

' with a printing-press, or separately.

Figure I is a side elevation of the machine.

' Fig. II is a perspective view of afolded sheet.

Fig. III is a top view of the machine with the feed-board removed. Fig. IV is a side elevation of the machine, showing the opposite side to that shown in Fig. I. Fig. V is a longitudinal section at V V, Fig. III, showing the parts in normal position; and Fig. V1 is a similar section showing the parts in operation. Fig. VII is a detail end elevation.

1 is a suitable frame having supportinglegs 2.

3 is a table, upon which the sheet to be folded is laid, being fed from the feed-board 4. The feed-board is joined at 5 to a vertically-adj ustable standard 6.

7 is a set-screw screwing into the tubular fixed part of the standard and having bearing against the movable rod forming the upper part of the standard.

9 is a screw forming the pivot of the hinge 5, and 10 is a thumb-nut, by which the hinge maybe made rigid.

11 is a rod having vertical reciprocation and pivoted at the upper end, at 12, to one arm 13 of a lever having arms 14 and 15.

16 is a cord or belt whose ends are connected to the ends ofthe arms 14 '15,, and which is coiled one or more times around a sheave or pulley 17 upon the shaft 18 of a roller 19. Above the roller 19 is a gravitating roller 20, whose gudgeons 21 turn-in boxes 22, which have vertical movement between guides 23. Y

24 are springs adapted to force the boxes 22 downward, so as to press the roller down,

upon the roller 19, or upon any object between the rollers. The shaft 18 carries a sheave 0r pulley 25, around which is coiled a cord or belt 26, which is also coiled around a pulley 27 upon a shaft 28,which carries a sheave or pulley 29, around which is coiled a cord or belt 30, which is carried around an idle-sheave 31 at the other end of the machine. The cords or belts 16, 26, and

should be coiled a number of times around J the pulleys 17, 25, and 29, and the coils should be 'made fast to the pulleys at one point,

so that they cannot slip on the pulleys. the lever 13 14 15 oscillates, the rollers 19 20 and the shaft 28 have rotary reciprocation. 32 is a slide or cross-head, whose edges 33 work in guide-grooves 34 of the sides 35 of the frame. The slide has a rearward extension or arm 36, slotted longitudinally at 37.

Through the slot 37 extends the screwthreaded end 38 of a bent rod 39, whose other end 40 is attached to the cord or belt 30, The rod 39 has on it a collar 41, which bears against the under side of the arm 36, and a nut 42 upon the end 38 bears upon the top of the arm 36, so as to fix the rod rigidly to the arm and cause the slide to move with the cord or belt 30.

43 is a push-plate supported on a rock- 51 is a bolt or stud set in the plate 49, ex?

tending upward through the slot 37, and carrying a nut 52, which bears on the arm or extension 36, and thus fixes the feed-plate rig: idly to the slideor cross-head, while at the same time it gives means for the longitudinal adjustment of the plate upon the slide. The plate 49 has pins 53, which extend downward through longitudinal slots 54 in the table. 1

The table has also a central slot 55, in which Works the drive-rod 39. .The rock-shaft44 (which carries the plate 43) has a depending arm 56, which, as the slide or cross-head 32 Ibo moves backward, comes in contact with an adjustable stop pin or stud 57 and turns the shaft, so as to throw the free edge 43 of the plate upward from the table to leave the way I clear for a sheet to be folded. I

58 is a fender or guide, by which the advancing edge of the sheet is guided between the rollers 19 20, and by which the front part of the sheet is held down in a proper position for the folding of the sheet. The tender or guide 58 is made removable, being held in place by two screws 59. It is not used when it is desired to give the paper a'single fold, for in such case the fender or guide is removed from the machine and the sheet passed down edgewise between the rollers 19 20 and the front edge of the table 4 until the lower edge of the sheet reaches an adjustable ledge 60, secured to the legs of the machine by bolts 61, that pass through lugs at the ends of the ledge and vertical slots 62, made in the legs.

The operation of the machine is asfollows: Where it is desired to make two folds in a sheet, as seen in Fig. II, the plate 43 is adjusted so that its front or free edge is distant from the pins 53 the width of one of the outer leaves of the folded sheet, and the slide or cross-head is so adjusted on the rod 39 that the free edge of the plate 43 will just reach the rollers 19 20 at their point of contact at its most advanced position. The parts, when the sheet is fed upon the table, are in the position seen in Figs. III, IV, and V. The rod 11 now moves upward and the cross-head or slide moves forward, the pins 53 pressing against therear edge of the sheet 48, and pressing its front edge between the rollers 19 20. These rollers are rotating in the direction indicated by arrows in Fig. VI, so that the edge of the sheet does not pass between them. As the movement of the cross-head carries the arm 56 out of contact with the stop 57, the free end of the plate 43 descends on the sheet 48, and as the cross-head advances a fold is made at the line on which the edge rests, which is carried between the rollers 19 20. lVhen the rod 11 begins to descend, the rotation of, the rollers 19 20 is reversed, and they turn in the direction indicated in Fig. V, so as to carry the sheet between them and press the folds, the front edge of the sheet and the fold made by the edge of the plate 43 passing through together and the other fold being made equidistant between the other fold and the front edge of the sheet as the sheet is about to leave the rollers. After a sheet has been once assed throu h the machine it' may be passed through again to cross-fold it. The manner of giving a single fold to a sheet has been hereinbefore described.

I claim as my invention- 1. The combination, in a folding-machine,

of the table 3, the pressure-rollers, as 19 20,

3. The combination, in a folding-machine, of the table 3, provided with slots 54, the reciprocating cross-head or slide 32, the pushplate 43, hinged to the cross-head, push-pins 53, connected to the cross-head and traversing the slots 54, and rollers 19 20, having rotary reciprocation, all adapted to operate substantially as set forth.
